Rough idle on cold starting


Registered User
Hi Guys,

Having a problem with my 2013 Avant 177 tdi, on cold mornings it seems to wind and wind until it fires up and then has a rough idle for about 5-10 secs.

could this be a glow plug issue? is there anyway to pre-heat the glow plugs on a cold morning?

any help is much appreciated.

Does have symptoms of a glow plug issue. Do you have any warning lights or anything?

You need to really have the ecu scanned for any faults

No there isn't anything that pops up, the car is still under warranty so will call up Audi on Monday.

There isn't anyway to heat the plugs is there? It all seems to start automatically when I push the key in the ignition.

Sounds like a typical glow plug issue to me. Do you not have a little glow plug light (that takes about 1 to 2 seconds to got out) when you first turn the ignition on? The light going out denotes the glow plugs being up to start-up temperature. It may take 2 seconds in this cold weather.
